We'd better add > instruction on the web GUI, so that user knows to adjust it by some rule. > > In the rowkey part, adding: > "Important: Dimension's positioin on HBase rowkey is critical for > performance. You can drag and drop to adjust the sequence. In short, put > filtering dimension before non-filtering dimension, and put high cardinality > dimension before low cardinality dimension." -- This message was sent by Atlassian JIRA (v7.6.3#76005)
